I forgot to put the battery from my charger back in my camera, so I used my phone, which doesn't handle wet surfaces well. Oh well.
I wanted to get out this weekend before the rain, so I took Thistle to walk in the Kettle Moraine State forest and associated sandy barrens/prairies and around Scuppernong Springs. I was hoping the Aristida species (four of them) on the sand prairies would still be holding their seeds, but they had all dropped.
prickles w/o broadened base, prostrate, +/- evergreen
buds pubescent throughout and greater than 6mm long
poor picture of small, hairy Berteroa rosette
Admittedly, the pictures aren't convincing in this season, but the the length of the flowering culms, growth habit, and in inflorescence (even with spikes fallen off) are fairly distinctive, especially in a dry, sandy habitat (other sedges, including Pensylvania sedge, were around).
stems glabrous, leaves petioled, marginal teath minimal, undersides of leaf pubescent, growing in interior of woodland
natural population at margins of sand prairie
These plants represent variety columbianum (not an INat option)
